Low Carbon M&E Project
Cookley Sebright School, Redevelopment

Project Overview

Remodelling of a school to deliver Low Carbon teaching space, including passive stack ventilation, and optimised natural lighting combined with high efficiency artificial lighting with automatic dimming controls - Awarded a BREEAM Very Good rating.

Worcester County Council are recognised as a leading Local Authority on sustainability and Low Carbon Strategy. Briar have been privileged to provide Low Carbon M&E Design and project management to WCC for over six years, developing schools, sports centres and general extensions/services design.

Description

Worcester County Council and the Cookley Sebright School wished to create new flexible, high quality teaching facilities through the remodelling of the existing school site. This included the demolition of an existing antiquated swimming pool/changing facility and the construction of six standalone key stage 1&2 classrooms (Phase 1), with the further addition of two nursery and reception classrooms plus a new main school entrance facility (Phase 2).

Keen to minimise the long-term environmental impact and to support the achievement of a ‘very good’ BREEAM rating, the Council required the new facilities to incorporate cost effective, practical low carbon M&E design to minimise long-term energy consumption, carbon emissions and running costs. This included the integration of high efficiency lighting with automatic dimming controls, gas-fired condensing heating boilers and a passive stack natural ventilation system, all controlled via an advanced BMS accessible by the Energy Manager at County Hall.

Briar were appointed as a result of our expertise and experience in the design of low carbon M&E services within the Education Sector and we are approved on the Worcestershire County Council M&E Framework.

The project was delivered in association with Quattro Design Architects.

Low Carbon M&E Project
King Edward VI Handsworth School for Girls, New Library

Project Overview

Construction of a purpose built new library as part of the school’s Centenary celebrations. The facility provides a contemporary study centre for pupils and the project included a number of low carbon technologies, including low energy heating using ground source heat pumps, high efficiency lighting and natural ventilation.

Description

Briar Associates have supported the seven Schools of King Edward VI in Birmingham for over 8 years with the provision of independent low carbon design advice, full M&E design and project management for many projects, plus infrastructure upgrades and asset condition surveys.

Briar Associates were appointed to provide expert low carbon feasibility advice, detailed mechanical and electrical services design and project management for the development of a new library at Handsworth School for Girls. The project successfully combined a modern and serene library facility with high tech, low carbon building services design.

To support the school’s aim of minimising the environmental impact of the new building, the build design integrated a number of cost effective, practical low carbon technologies, including ground source heat pumps that absorb heat from underground via a borehole system and serve a low energy underfloor heating (this technology benefits from the Renewable Heat Incentive). Other features include low energy lighting with automatic daylight dimming controls, a Monodraught natural ventilation system and an advanced building control system that manages the various energy savings features. The result is a building that has minimised long-term energy consumption, carbon emissions and ensured low running costs throughout its lifetime.

The new library supports teaching and learning by providing a collection of resources relevant to the curriculum and wider personal interests. It creates a place of equal access for all, providing a flagship, low energy learning facility for both staff and students. The development also demonstrates how cutting edge low carbon technologies can be successfully and cost effectively integrated into modern teaching facilities. The project was delivered in association with Crouch Butler Chartered Architects, Birmingham.

Project Main Features

  • Low energy (borehole) ground source heat pumps serving an underfloor heating system
  • Integrated natural ventilation system with Monodraught Windcatchers
  • Low energy lighting design (12W/m2) with automatic daylight dimming controls
  • Bespoke heating and ventilation control system
  • Solar shading roof design to ensure comfortable summertime temperatures without air conditioning

Heating System Carbon Saving
Brighton General Hospital

Project Overview

Briar Associates initially carried out a technical feasibility study and financial appraisal co-funded by the Carbon Trust to assess the practical options and energy saving potential from decentralising the outdated steam boilerplant, distribution and condense return systems at Brighton General Hospital.

Sussex Community NHS Trust further engaged Briar Associates directly to support the implementation by providing detailed M&E design and project management services.

The programme involved replacing large inefficient central steam boiler plant and distribution systems with high efficiency independent local condensing boilers with fully automated building management control system to provide centralised heating control across the site. The domestic hot water calorifier systems were also replaced by a mix of high efficiency plate heat exchangers and point of use water heaters, significantly reducing secondary circulation losses.

Key Details

  • Major steam decentralisation, boiler replacement and infrastructure upgrade project
  • £1.4m project cost delivered over 2 phases 2008 – 2010
  • Complex project delivered in working hospital
  • Annual cost savings of approx. £130,000
  • Approx. 1,000t annual CO2 savings
